PREFACE

1. MES Schedule of Rates 2016 (RATES AND SPECIFICATIONS) has been prepared under instructions and guidance of Engineer in Chief, Army Headquarters, Dhaka Cantonment to replace existing booklets - MES Schedule of Rates 2012 and Schedule for the Rate list of Furniture & the Rate list of conveyance of materials 2012. Besides updating the price, incorporation of modern technology was also taken into consideration to revise the schedule. Accordingly some items have been added/omitted. MKS system of measurement has been used in most of the places. Necessary conversion tables and data have been incorporated for consultation and ready reference.

2. The rates will be valid only if specifications given in the Schedule are strictly followed. However, if it is necessary to deviate from specifications, prior approval of the respective DW & CEs will be required. In case of disputes regarding application of any rate, the decision of E in C shall be final.

3. The specifications and rates will be valid till a new replacement is done. The rates will be reviewed from time to time. DW & CEs will forward proposed amendments with necessary data and analysis on 1st of January and July each year to E in C's Branch, who will arrange pre-audit, approval and will issue amendments, if considered necessary.

4. Reproduction in part or whole of this Schedule by any individual, Department, Contractor or Firm, etc. is prohibited. This Schedule may, however, be used by any individual, department, etc. provided the Contract Agreement makes a clear mention that the contract has been based on MES Schedule of Rates 2016.

5. We thank MES officers and staff who have worked whole heartedly to revise this MES Schedule of Rates 2016.

6. This schedule is supported by a programmed analysis of rates as per item of works.

7. Special thanks to E in C for his valuable guidelines to modernize the MES construction works and the furniture, who has also been kind enough to approve the MES Schedule of Rates 2016, which will be effective from 1st May 2016.

(2) Aggregate are made out 1st class bricks of 19mm grading. Lime is unslaked/stone lime. Surki is out of first class bricks and insoluble in water.

(3) All ingredients are to be mixed thoroughly. The mixer is kept for about 10 (ten) days until an adhesive/semisolid bond is developed among the ingredients. During this period whole mixer is turned twice/thrice and lime water is added as per requirement. Precaution is taken to save the materials from sun & rain.

(4) Before applying the terracing, the surface of the roof is cleaned and lime concrete is laid in single layer about 20% thicker than specified for consolidation with slope towards gutter.

(5) The lime concrete is then thoroughly consolidated by beating with wooden mallet. The beating is to be systematic by lengthwise. Movement of labourers from one end to other end on the entire width of the roof.

(6) While the beating of concrete is going on the surface of concrete is frequently sprinkled with lime water and a mixer of molasses, Catechu and boiled solution of Methi seeds for 9 sq.m surface area of 75mm (av) thickness, 50 Litre solution is taken. Solution is prepared by dissolving 4.0 kg of lime, 4.50 kg

RESTRICTED

RESTRICTED

f. Foam-Lub used in Plastering-Mortar. Apply 500 ml. of Foam-Lub with mixture of 1 bag of cement to prepare mortar for plastering. Use the sufficiently wet mortar. Apply curing for 7 days with normal mode. Apply one coat of Desalt- S01 as sealer on dry plaster before putting and painting.

g. Method of Mixture of Desalt-S01 as Sealer. Desalt-S01 + Water + Catalyst = 1 Liter + 4 Liter + 25 m.l. or 1 mark. Apply the mixture properly with a jute brush. Apply the mixer within 2 hours of preparation. Don’t apply Desalt-S01 on wet plaster. Any other sealer is useless after using Desalt- S01.

72. Chemicals used to Prevent Salinity, Water Absorption and Growth of Algae on Sand Stones, Ceramics and Ordinary Fine Bricks of Old Building.

a. Chemicals to be used Sequentially.

(1) Foam-Lub used in pointing mortar

(2) Desalt-S01

(3) Hydro Seal Ef-34 ( with water)

b. Method of Preparing and using Chemicals.

c. Foam-Lub used in Pointing Mortar as Site Preparation. When the casting of sand stones, ceramics, and ordinary fine bricks is finished, generate the mixture of 2 liter Foam-Lub, a bag of (50kg) cement and appropriate amount of water to generate mortar. Use the mortar to fill up the joints of mortar with the mortar so that the water can’t penetrate through the joints. Clean loose materials, if any, with brush and water.

Pestonal-A + 100 ml. Pestonal-B + 10 Liter water Use a funnel to pour above mixture of 500ml. Then seal the holes with mortar. Though , hacking up floors is the best way of prevention of this kind of problem, this is an effective method of prevention of insects.

d. Methods of using Pesto-Clea for Destroying and Preventing of Termite on Old Wooden Furniture, Windows, and Doors. The Method of Mixing and Preparing Pesto-Clea (Termite Controlling Liquid). Mix Pesto-clea-A 150 ml. + Pesto-clea-B 150 ml. + 5 Liter water properly. Then it sprays on whole wooden materials with a spray machine or hair-brush.

bricks and to be of approved manufacture.

c. Size of Bricks:

(1) Burnt bricks shall be not less than 240mm X 120mm X 70mm.


complying in all respect with BDS EN 1997-1: 2003 CEM-I. Cement, unless otherwise

Burnt bricks built in mud mortar will only be dipped in water before use. The joints of brickwork

shall be not less than 6mm or more than 9 mm in thickness. All joints to be well flushed up at every

course. The wall shall be carried up regularly, not leaving any part more than 1 metre lower than

another, unless special circumstances render this impracticable.

Any walls left at different levels to be raked back, courses to be properly leveled, perpends,

quoins, jambs, and other angles plumbed, as the work proceeds. All brickwork shall gauge four

courses to 300mm in height including joints. In alteration work the brick work shall gauge with

existing work unless otherwise directed; Internal walling and backings to be in even courses with

external facings, but bricks may be thicker and joints thinner, provided the courses bond with the

work. All brick work to be built in English bond, unless otherwise specified. No half bricks or bats
